Dark Crystal

The Homo Sapiens Dark Crystal is an exceptional fountain pen, showcasing all of the unique benefits of the original, award-winning Homo Sapiens with several upgrades and modifications:
 
Smoky Crystal Ink Chamber: The most discernible modification to the body of the pen is the addition of a large transparent window made from acrylic resin. A large section of lava has been cut out of the pens body and replaced with a piece of smoky acrylic tube, transforming the pen into a demonstrator with a unique appearance and identity. This 'oversize' window offers the user a view of stored ink inside the pen and the pens 'double reservoir' power filling system 
 
Double Reservoir: The original Homo Sapiens featured Visconti's 'single reservoir' power filling system. The Dark Crystal is upgraded to Visconti's patented 'double reservoir' power filler, a vacuum filling system that is easy to use and has considerable benefits. Patented in 1998, this is arguably the most advanced filling system ever developed in fountain pen history. The user is able to fill the pen with the equivalent of 10 cartridges of ink, and thanks to the two reservoirs, prevents ink from leaking during air travel. 
 
Smoky Crystal Ring: The final change is the small ring around the pens grip section. Metal has been replaced with smoky acrylic resin, offering a view of stored ink in the pens second smaller ink reservoir.
